膜面环口与下方接水面

提示词

在雨态景观概念中，让膜面向选定中央环形开口收拢，可见水线从该处下落到对应接水面；分清膜面、环口、水线和接水边界，不用雨链、立柱或整片水幕替代这组关系。

In a rainy landscape concept, draw the membrane toward the selected central ring-shaped opening, with visible water strands falling from it to the corresponding receiving surface below. Distinguish the membrane, opening, water strands and receiving boundary without substituting a rain chain, column or continuous water curtain.
